This time around, we’re back in the US with a much smaller system, mostly centered on bank burglary with a side of sprinkler monitoring. The building in question is a sprinklered 3 story single stair corner building of joisted masonry construction with a bank on the ground floor and apartments on the floors above, located on a small town’s Main Street.
Bank Intrusion
The bank is protected by a UL Extent 2 bank burglary system consisting of:
- A Honeywell Vista-20P, mounted in a VISTA-ULKT enclosure inside the vault and wired to:
- A 6160 keypad located behind the teller line via an ECP-ISO isolator mounted in the panel enclosure
- A pair of 18 Ah batteries with a SA5140-1 harness to provide upwards of 72h of standby
- A Honyewell LTE-HSV communicator via the ECP bus
- And a Honeywell AB12M motor bell, with bell supervision on the panel enabled.
The bell is mounted outside above the ATM and the communicator is located in the IT closet behind the conference room in order to provide adequate cellular signal without relying on external antennae. The communicator also has a 72 hour auxiliary supply, consisting of:
- an Altronix AL125ULB set for 12V and powering the communicator from its auxiliary output
- in a VISTA-ULKT attack enclosure
- with 2 more 18Ah batteries wired in parallel to it.
The panel’s zones are wired as follows, with Zone 1 in EOL mode and the remaining zones set for double-balanced operation:
- Zone 1 is the panel tamper loop, set for Trouble by Day/Alarm by Night and providing tamper protection for the panel, bell, and communicator as well as the communicator fault output
- Zone 2 is the vault zone, set for 24h protection and connected to:
- Honeywell SC100 vault seismic detectors on all six sides of the vault and the vault door, with the tamper contact connections looped back through the cable
- A FDD 7050-C vault heat detector located over the vault door
- And a high-security contact on the vault door, with a shunt lead coming in from the vault lock’s shunt contacts
- Zone 3 is the ATM/night depository zone, also set for 24h protection and connected to:
- Honeywell SC105 seismic detectors on the door and body of each safe/chest,
- Lock shunted contacts for each safe/chest door,
- And the head protection contacts on the night depository. (The ATM head uses a high security lock, but is only otherwise protected by a contact connected to a discrete input on the ATM computer.)
- Zone 4 is set for interior protection and connected to high security contacts on all interior doors, including the doors to the sprinkler and IT/telecom closets, and yes, the bathroom door too
- Zone 5 is the entry/exit zone for the high security contacts on the front door
- Zone 6 is an immediate perimeter zone, connected to FG1625RFM glassbreak sensors in the lobby, offices, and conference room to protect the windows there as well as the door glazing
- Zone 7 is the motion zone, set as an interior follower and connected to anti-mask dual tech motion sensors (Bosch ISC-PDL1-WA18Gs) in the conference room, offices, vault, and lobby, with their mask contacts wired as series tampers in the doubled-back tamper loop
- And Zone 8 is a 24h silent zone connected to Potter HUB-T double-action holdup switches inside the vault and at the teller stations, as well as the ambush outputs from the vault, ATM, and night depository locks.
There are Honeywell SC115 remote test transmitters located at opposite corners of the vault to provide a test facility for the seismic detectors. These transmitters are wired to a DPDT momentary keyed test switch inside the vault that also shunts out zone 3 via an EOL resistor for the duration of the test.
The bank also has two POE IP cameras with SD cards for local recording in it; one of them is a 360° fisheye ceiling camera that sees the entire lobby, while the other is a dome camera tucked into the back of the vault with a good view of the vault door.
Sprinkler Monitoring
Zones 6 and 7 on the communicator are configured for EOL operation and connected to the building’s waterflow and sprinkler supervisory switches, respectively, providing them with 24-hour central station supervision, thankfully at no extra charge. There is also a 120V motor bell on the outside of the building, sharing a circuit with the alarm panel and communicator, that provides external notification of fire sprinkler waterflow.
Residential Fire
The apartments are fitted with standard 120V/9V interconnected smoke alarms, nothing more. The doors do have commercial-grade (LCN 4040) closers on them, although without holders for security reasons.
Residential Access Control
The inner door to the residential area stair vestibule is governed by a DormaKaba PowerPlex 2000 self-powered (energy harvesting) electronic lockset paired with a Von Duprin LDXP98 rim exit device and an Abloy KIK cylinder for key override. This provides access for residents and servicepeople, while a basic wired doorbell shared among the units and a peephole in the door is sufficient for visitor access in a building this small.
Individual apartment locking is handled using Schlage L9453s on the apartment doors, with a good grade of mortise cylinder fitted to them.
